core-piece 19 of soft metal. Each core 19 is arranged to slide within atube 20 of brass or other suitable nonmagnetic material which extendsthrough the spools of the solenoids and projects below the same to aconsid- .erable extent;

wound that when energized the cores l jalllgthe racks 21 and 22 aredrawn downwardly, and by properly energizingone or the other of saidsolenoids, the typewheel may be rotated in one or the other direction.Each solenoid core 19 (see Figs) rests upon the head of-stop-plunger 27,arranged within the tube or cylindel 20. The stem of the stop-plunger 27extends through a cap 28 upon the end of the tube 20, and a spring 29coiled about the stem eiftcnds between cap 7 28 and the head of thestop-plunger to yieldingly hold the latter in position. The position ofthe sto'pplun-' ger 27 and the tension of the spring 29 may be properlyadjusted by rncans of the cap 28 and a thumb-nut 30, which areadjust-ably threaded upon the ends respectively of the tube 20 and thestem of the plunger. Thumb-nut 30 is ofcourse held into engagement withthe cap-piece 28 by the spring 29. A lock-nut or stopmember 31, having arounded lower end isthrcaded upon the extreme lower end of thestop-plunger stem, as shown. By this arrangement of yieldingstop-plungers, which areheld against movement in one direction, butyieldin opposite directions, the type wheel and rotating shifters therefor,may be held in central position, but are free to be actuated to rotatethe type Wheel in opposite directions from normal against the resistanceof one or the other of said stop-plungers. Moreover, the stop-plungersmay .beladjusted to socurely', yet yieldingly'hold the type wheel incentral position so that all back lash or lost play between theconnected parts is taken up.

The rotating of the type wheel in each direction is variably arrested inone direction by a set of stop-arms G, 0 C and G, and-in the otherdirection by a set of stop-arms D D and D, which, in the form shown, arearranged respectively beneath the solenoids B, B and shiftable into thepath of novcment of the stopmembers 31 upon the ends of thestop-plungers 27, to

i variably limit the movement of the corresponding shifters operated bythe solenoids.

The separate sets of stop-arms and the operating de -wices'therefor,arc-alike except that they are oppositely arranged beneath the separatesolenoids as shown.

65 circuits of the solenoids B and B.

Each set is arranged upon a suitable support 32, se- 1 contacts extendsbetween the corresponding set of stopcured to the front face of theframe platelO. A pair of roelt-shafts 33 and 34 (see Figs. 3, 4 and 5)are journaled between forwardly extending lugs or brackets 35 5 upon thesupports 32, and the stop-arms O, C are socured to the inner ends of theshafts, while the stoparms C C are secured to the inner ends of sleeves36,

3 7 loosely mounted on the shafts but held against longitudinal-movementthereon by collars 38.

The stop-arms are oppositely arranged, that is to say, stop-arms C and 0on shaft 33and sleeve 36, respectively, are normally held in front ofthe path of move ment of the abutment 31, with which they cooperate toarrest the movement of the corresponding shifter,

while the stop-arms C and Con shaft 34 and sleeve 37 lie inside of thepath of abutment 20. Operating electro magnets E and E are arranged;uponthe support. 32 above the shafts 33 and 34 and their armatures arecarried upon arms d and d secured respec- J tively to and extendingupwardly from the outer ends of the shaft 33 and the sleeve 36. Electromagnets E and E are arranged below the shaftsand their correspendingarmatures are mounted upon downwardly projecting arms d and d securedrespectively to the outer ends of the shaft 34 and sleeve 37.-

The stop-arms are similarlyconstructed and each corresponds toupper andlower sections 39 and 39. The lower sections 39 have hub portions 40secured to the corresponding operating shaft or sleeve, while the uppersections 39 of each arm has a laterally projecting stop-lug 41 at itsupper end. The upper and lower sections are adjustably connectedtogether by pin-and-slot connection 42, and screws 43 connected to cars44 upon the upper section and threaded through cars 45 upon the lowersection, serve to properly position'the stop-- lug 41 at the outer endof 'the stop-arm. The hubs of theseveral stop-arms are provided withdownwardly extending ,lugs 46, between which .extend tension springs 47.

By selectively controlling the energizing circuits of the electromagnets E, E E and E the outer stoparms-'() and C may be shiftedinwardly and the stoparms (3 and C shifted outwardly against the tensionof springs 47, to bring the corresponding. stop-lugs 41 at their upperends into the path of movement of the shifter operated by the solenoidB. The stop-lugs 41 are located at different distances below the ends ofthe shifter so as to variably arrest the rotation of the type wheel. i

The stops D, D D and Dand their operating magnets F, F F and F aresimilar in construction and arrangement and cooperate with the shifteroperated by the solenoid 'B to variably limit the rotation of the typewheel in the opposite direction. -By the arrangement of the solenoids Band B, the corresponding,

\ shifters and sets of stops, the type wheel may be rotated in-oppositedirections from normal to select any one of the longitudinal row of typethereon.

The energizing circuits of the solenoids'B and B are preferablycontrolled, each by the corresponding sets of stops or the operatingcircuits therefor For this purpose, pairs of normally openspring-contacts 48 and 49, mounted upon but insulated from lugs 50 onthe supports 32 areinterposed respectively in the energizing Each pairof springtate the type wheel todcsired position.

arms so that when any one of them is shifted, the circuit through thecorresponding solenoid is also closed. The contacts 48 and 49areprovided with insulating strips 48 and 49 against which the stop-armsstrike.

It is therefore only necessary to selectively control the.

energizing circuits of the stop-actuating magnets to ro- The lateralshift of the type carrier or wheel is effect.- ed in the form shown inFig. 1 by a pair of electro magnets or solenoids G, G, arrangedhorizontally and in line as shown, and secured at their inner ends to aU- shaped piece 51 which, in turn is mounted upon an upright projectionor lug 52 at the upper edge of the frame plate a. Lug 52 is offsettoward the front and solenoids G, G are as shown, arranged in front ofthe racks and pinions by which the type wheel is rotated.

The solenoids G, G are alike and each comprises a spool 53, surroundedby a rectangle 54 of soft iron. A core-piece 55 common to bothsolenoids, is arranged to slide within theinner ends of a pair ofcylinders or tubes 56 of brass or other suitable non-magneticmaterialarrangodwithin the solenoid spools, as shown and projectingbeyond the outer ends thereof. A shifter-arm 57 fixed to the centralportion of the core 55 and pro-. jecting rearwardly and upwardlytherefrom, has a slotted or forked end engaging a grooved collar 58 onthe type wheel. By energizing one or the other of the solenoids G or G,the type wheel may be shifted laterally in opposite directions fromnormal.

The type wheel and the lateral shifter therefor, are

yieldingly held in central position between a pair of spring-held stops59 (see Fig. 2), similar in all respects to the stop-plungers 27. Thesestops or stop-plungers 59, are arranged within, the tubes 56, engage theopposite ends of the shifting core 55, and are yieldingly held inposition to center the type wheel in lateral direction by springs 60,coiled about they stems of the stop-plungers and extending between theheads thereof and the eap-pieces 61 threaded over the ends'of the tubes56. Thumb-nuts 62 adjustably threaded upon the stems of thestop-plungers, engage the cap-pieces 61, limit the inward movement'ofthe plungersand hold them in normal position. By adjustingthe-cap-pieces 61 and nuts 62, the positions of the stop-plungers 59 arepronerly adjusted to securely hold the type wheel in centralposition andtake up all lost play or back lash between the parts.

The extent of lateral shift of the type wheel is limited .in onedirection by the set of stops H, H and in'the opposite direction by theset of stops .T, J, the stops being arranged to'engage abutments 63adjustably threaded uponthe projecting endsof the stem of thestop-plungers 59. Both sets of stops and the controlling devices Itherefor, are similar in construction and mounted upon supporting plates64, which are fixed to the upper, front portion of the frame plate a.Stop H is fixed to the support 64, but stop H is in the form of ashiftable arm. The latter is provided with a laterally projectingstop-lug 65 on'its end normally out of the pathof the adjacent abutment63,.but arranged to shift into position between the abutment and thestop H, Stoparm H is mounted upon a rock-shaft 66,.journaled between apair of brackets or lugs 66 on the support 64, and provided with ,alaterally projecting arm 65 to mounted upon but insulated .plate 64 inthe path of movement of the stop-arm H,

which the armature of the operating magnet K is secured. Magnet-K ismounted as shown uponthe support 64.

A pair of normally open sp ng contacts 67 are so as to be shifted toclosed position when the electro magnet K is energized. These contactsare interposed in the energizing circuit of the adjacent solenoid G,

whihserves to shift the type laterally.

The stops. J,- J

sitely arranged to variably arrest the lateral shift of the type wheelin the other direction. Stop-arm J is arranged to engage and close apairof normally open spring-contacts 68 interposed in the energizingcircuit The contacts'67 and 68 are provided with insulating pieces 69-against which 'the of the solenoid G.

stoparms H and J strike.

.By closing the energizing circuit of one or the other v of thesolenoidsG or G, the type wheel may be shifted laterall mesa, ergized,either the stop H or J is operated, the circuit through the adjacentsolenoid G or G is closed and the type wheel is shifted laterally asbefore in one or the other direction, but is arrested by the engagementof.

one of the abu'tments 63 with the stop-lug 65 upon .eithei" one of thestop-arms H or J. By this means, the type wheel may be quickly shiftedendwise in opposite directions from normal audits shift is variablyarrested by the stops to bring any one of the-lateral rows of type uponthe wheel to-printing position.

At the'tdp of the' fiaine plate a is arranged a horizon-;

tal platform or top plate 70, which extends rearwards,

' as shown in Fig. 3. An upright portion 71, at the extrcmerear of theplatform 70, carries the printing ham mer. M and the operating magnet Ntherefor. The

printinghammei M is upon the arm of a bell crank 72, arranged. to swingin a horizontal plan upon a pivot- 73., which is carried upon' ahorizontal support 74,

V projecting forwardly from the upright 71.

The actuating magnetN is preferably in the form of a solenoid and iscarried by horizontally arranged U-shaped support fixed to the outer endof the up right 71 andforwardly projecting therefrom. w This. solenoidco'mprisesa spool 75.sur.-.undedlby arectam gular piece 76 of soft ironand provided with a shifting core-piece 77. The inner end of thecore-piece or 50 shifter'77 is provided with a fixed collar 78 and a.

loose collar 79, between which extends the'forked end of the short armof the bell crank" 72. Collar 79 is yieldingly held in position by acoiled spring 80 which extends betweenv the collar and a nut '81adjustably threaded upon the end of-thezshifter 77. A lock nutorstop-member 82, having a rounded outer end is threaded upon the extremeend of the shifter 77 and holds nut 81 in adjusted positionfyrl stopscrew 83 isadjustably threaded through a stud 84,

projecting forwardly from the upright 71 and. is

1 ranged in the path of the stop-member 82.

when the solenoid N is energized, the core-piece or shifter 77 isactuated to move the hammer M toward the type wheel A. The stop-member82 upoii the 65 shifter is arranged to engage the stop-screw 83, beforemm the supporting v and the operating magnet L for thestop-arm'J, aresimilarly constructed but are oppoin enebr'the other direction untilarrested by H or J. If either of the magnets K or L is enthe hammer.strikes the wheel. The hammer is however, not arrested but thespring-held collar 79 permits it to continue its movement under the'influence of the momentum acquireduntil the blow upon the ,type at theprinting point is struck to effect theimpression thereof upon the paper.The blow is thereby rendered sharp and quick. 7 Each of the'shifters ofthe solenoids B, B, which rotate the type wheel, is also'arranged toclose the energiz'ing circuit of the'solenoid N whichoperate's theprinting hammer. For this purpose, a pair of normally openspring-contacts 85 (see Fig pl) are mounted upon. an arm 86, but areinsulated therefrom as shown. Arm 86 is pivoted to the lug 50 on thesupporting plate 32. A spring 87 extending between the end of. the arm86 and the plate 32 holds the free ends of the contacts into engagementwith the stop-member 31 on the lower end of the shifter of the solenoidB and above the set of stops C, C and C. Whenever anyone of the latterand the shifter of solenoid are operated, the conta efs 85 and arm' 86are swung about the pivot of the arm until arrested by the engagement ofthe free ends of the contacts with the selected stop. The contacts arethen brought into engagement to close theenergizing'circiiit of thesolenoid N and to operate the printing hammer M. 'lhefrodends of thecontacts 85 are provided with insulating strips 88 with which thestop-members 31 on the shifter of solenoid Bv and the stop-lugs 41 ofthe arms C, G etc. engage. I

A pair of contacts 89 similar in construction and arrangement areinterposed in the circuit of solenoid- .'N and cooperate iii a similarmanner with the shifter of solenoid B and the set of stops D", D, D andD. A pair of normally closed spring-contacts 90 (see Figs. 2 and 2") aremounted upon but insulated from the rectangular piece 76 of the solenoidN. A bell crank 91 is pivotally connected toa bracket 92 upon the outerend of rectangular piece 76. One end of the bell crank is forked andextends between a pair of collars'93, adjustably threaded upon the outerend of the shifting mire-piece 77, and its opposite end is arranged toengage one of the spring-contacts 90, and break the engagement thereof,wheriever the solenoid is energized.

(ontact-springs 90 are interposed in the energizing 11o circuit leadingto the operating magnets and solenoids,

so that as soon as theimpression of the selected ty'pe is made, thecircuit is broken and the several magnets and solenoids are denergizedto permit the return of the shifted parts to normal position. The typewheel is quicklyreturned to normal by the springfactuated stop-plungers27 and 59'.

i The paper upon which the messages-are recorded is carried in the rearof the type wheel A, and intermediate the same and the printing hammerM, upona carriage 0 (indicated in dotted lines in Fig. it) arranged toslide transversely upon'the plat-form 70.. -,The papera carriage may beof any suitable construction, and any suitable meansmay be employed forshifting the same laterally or in' letter-space direction'.step-by-step'at printing hammer actuating each operation of the printing mechanism.So too, the

paper carriage may be provided with any suitable form of paper feedmechanism to properly fonn' the spaces between the lines oi printedmatter.

It will be obsenved that the mechanism for rotating 186 the. pathof thesnm-nn-mla-r 63', and moves contacts 68. A circuit is then closed frombattery by power wire 9th conductor 97, contacts (i8, conductor '98 andbranch 2 through the solenoid G, and back to and laterally shifting thetype wheel, is entirely in front of the wheel and in front of thesupporting platform 70, and that the printing hanuner is mounted above.the path of movement of the carriage upon the upright 7i at the rear ofthe platform. Ample space is thus provided for the laterally shift-ablepaper carriage. Moreover, the paper I (see Fig. 3) is held in v rticalposition at the rear of thetype wheel and in front of the horizontallyarranged printing hammer, so that the message may be (amveniently readas soon as it is recorded by any one in front of the machine.

I A diagram of the operating circuits is illustrated in Fig. 7, Theseveral operating magnets and solenoids derive current from a localbattery 94 and are connect ed on one side thereto by a. series ofbranches and a common return conductor 95, indicatethby heavy lines in.the diagrmn.- The operating magnets and solenoids in Fig. 8 and-will behereinafter described.

A power wire or conductor 96 leadsffrom the local baiteiy 94 to'theelectric selector means and back tln'ough'mie of the branches and one of.the magnetsor solenoids in accordance with the operationof the sclector means. The normally closed spring-coniacis90 are.

interposed .in the g-o nluctor 96 as shown. The circuit is firstclosedtln'ough one of branches 2,-3-or 4, lcadin respectively to'thesolenoids (if, magnet l,, magn t K and solenoid G. if the circuit isclosed directly by branch .I into the solenoid (i. thetype-wheel isshifted to theleft until arrested by the engagement of the stopmember615, with the stop J. lly closing thecircuitf through branch 2,-andmagnet I, stop I is shifted into into engagement.

If one of the four type in thisrow is desired, the hannner M is operated direct-i y after the sideshiftof the Wheel, by closing the circuit through the branch 15 and solenoidN,- to effect the impression of the selected type upon paper. If one ofthe type to be brought to the printing point is in one of the otherlongitudinal rows, the type, wheel must be rotated after the side shift,by closing the energizing circuit through one of the branches b.'6, 7,8, 9, l0, 1], l2 and through one of the stop-actuating magnets E, F E,E, F, F-,'F or F which are respectively connected to the severalbranches on one side and to the re urn conductor 95 upon the otherBranches 5, 6, 7, audit also control solenoid B, since whenever one oithe set of magnets F, F F and F" is energized, one of the stops D, D'-,D or D is shifted into the path of the stopmember 3i. to arrest themovement of the shifter actuated by solenoid 13, the shifted stop alsomovescontact 49 into engagement and closes the energizing circuitof'solenoid B as follows, from battely by power wire 96, conductor10l,contact's 49, conductor 102,

In a similar manner magnets I 15", If) and E operateto shift any one of the set of stops (3, C or G into the path of thecorresponding stop-member 31 to limit the movement of the shifter ofsolenoid B and shift contacts 48 into engaigement to close the circuitthrough solenoid B, as follows;---from power wire 96, conductors 99 and103, contacts -48, conductor 104 to the coil of solenoid 13 and bachtothe battery by return conductor 95. By

this means, the type wheels may be? variably rotated in theoppositedirection.

Similarly} theshifter of solenoid -ll moves contacts 85 into engagement-to close theprintinghammercircuit as follows:- from power wire So, by coininclors 99and 107 to contacts 85, conductor 108 and branch conductoi 13 thronghthecoil of solenoidN as before. In this form.

the type wheel may be shifted laterally to the right, or

left. one or two steps, to bringany one of four transverse rows of typein line with the printing hanuner, and retated 'inone or the otherdirection, one. two, three or four steps to bring any one of eightlongitudinal rows of type to the printing point, 'fhelongitmlinal row oft e in line with the-hammer ma. also be utilized 'so 7 that the typewheel may be ,provided with thirty-six characters in all. Tho-number ofstops for variably arresting the rotation and lateral shift of the typewheel, may of course be varied as desiredfsb that more or lesscharacters may be employed. Whenever the printing hammer solenoid N isenergized, contacts 90 are disena 'aqed bv the. shift of hell crank 72and the )(IWtT circuit is broken atthis point so that all parts mayquick-l y return to normal position and are ready to record thesin-(routing character. I

In theform shown in Fig'. 6, the ,type wheel N is similarly mounted upona' shaft 1) at the upper portion of the frameplate a, and is arranged torotate with the shaft and shift laterally thereon. The rotation of thetype wheel in opposite directions is effected by a horizpntal shifterarm-109, carried upon a pivot 110 at the upper end of a standard 111.Standard 111 is mounted as shown, upon a horizontal supporting plate 112fixed to the upright frame plate A. A toothed segment 113 is mountedupon a short rock shaft 114 carried between the upright a and a; secondupright 11 upon the frame. Segment 113 meshes with the teeth of a pinion115 upon the typewheel shaft b and is connected by a sides of thestandard 111' and the armatures of these magnets are fixed to theshifter 109 on opposite sides;

of its 'pivot. By'energizing one or the other of said magnets, the typewheel maybe rotated in one or the other direction. The type wheel A isheld in normal central position by a pair of stop-plungers 117, arrangedwithin vertical guide cylinders or tubes 118 mounted upon the support112. The stems of the stop-plungers extend through plugs 119adjustablythreaded into the upperends of the tubes 118, and also extendloosely through slots in the shifter-arm 109. Stop nuts 120 areadjustably threaded upon the upper ends of the stems of thestop-plungers and engage the upper edge of, the shifter-arm. Lock-nuts121 hold the stop-nuts 120 in place. The stop-plungers, shifter-arm andtypewheel are yieldingly' held in place against bottom plugs 119 incylinders 118 by springs 122, coiled about the stems of thestop-plungers 117 and extending between'the headsthereof and the plugs119. By ad.

justing the latter, springs 122 may be placed under proper ten'sion.- Byproperly adjusting the stop-nuts 120, all loose playlor back lashbetween the parts may'b'e taken up and tho shifter-arm 109 and typewheelA accurately held in central position. The sets of stops C, C", l and Cand the stops D, D'-', D and D for variably limiting the extent ofrotation of the type wheel in either direction, are entirely similar inconstruction and mode of operation to those employedupon the form shownin Fig. 1, and are. arranged on opposite sides of the projecting endofthe shifter arm 10.) to limit its movement in either direction. Thecontacts 48, arranged to be closed by anyone of the stops-Q, O, C or (1*are interposed in the circuit of magnet li and contacts 49 controlled bythe stops D,

I), 1) and D are interposed in the circuit of magnet 13. In this formhowever, additional stationary stops and D" are fixed to the supports32, respectively, below and aboye the sets of movable stops and byclos-' in g the energi zing'circuits by either .niagnet B or magnet 15,independently of the shiftable stops, the arm 109 may be moved in one orthe other directioninto ongagement with one or the other,of thestationary stops C or D 1 The pairs of contacts 85 and $9, for closingthe printing hammer circuit, are held by the springs 87,

a into engagement with the end of the shifterarm 109,

so that this circuit is closed whenever the arm 'is moved inoither'direction.

The printing hamnier, operating means therefor and paper-carrying meansin rear of the type wheel (not shown in Fig. ,6) is entirely similar inconstruction and arrangement to that'already described. In this form.

the type wheel maybe rotated in one or the other direction, one, two,three, four or five steps, and since the row of type inline with theprinting hammer may be utilized, the type wheel. may be provided witheleven longitudinal rows of typ'e. The type wheel in this form, isshifted laterally in one direction only. Shifter 55and solenoid G formoving the type wheel laterally toward the left, are entirely similar inconstruction and arrangement to that previously described, except thatthe type wheel and shifter are held against movement toward the rightfrom hormal position by a stop-screw 122 adjustably threaded through alug 123 on the bracket 51. Stops J, J for limiting the shift ofthe typewheel to .the left are similar to those previously described.

An additional. movable stop-arm J 2 is provided, having its stop lug inadvance of that on thestop-arm J. This stop-arm is secured to a shaft 66journaled in lugs 66 and 67 and extending through a slot in the stop-armJ. The armature of a magnet L is fixed to an arm 68 on the shaft 66 sothat the stop J 2 is shifted into the'path of the stop-member 63 whenmagnet L is energized. Stop-arms J and J 2 are arranged to close theenergizing circuit of the solenoid G by shifting the contacts 08 intoengagement in the manner previously described. By this means, the typewheel may be shifted to the left, one, twoor three steps, and as the'transverse row of type in line with the printing hammer may be utilized,the type wheel may have four transverse rows of type as shown. As thereare eleven longitudinal .rows, forty-four characters may be employed,any one of which may be broughtto the printing point by properlycombining the lateral and rotary mi'ivements of the type wheel.

A diagram of the operating circuits is illustrated in Fig. 8. As before,the current is derivcd'from a local battery 94 to which the severaloperating solenoids and magnets are connected on one side by thebranched return conductor 95 indicated by heavy lines. On the otherside, the several solenoids and magnets are connected to a set ofbranches, (numbered 2 to 15 inclusive) which are controlled by suitableelectric selectivemeans. A power wire 96 leads from the battery to thesolenoid G is closed, the type wheel is shifted to the left untilstop-n1ember 63 engages the fixed stop J and the fourth transverse rowof type is brought to the printing point. If the circuit is closedthrough branch 3 or 4'and magnet L or L, either one of the stops J and Jis shifted into the path of stop-member 03. At the same time contacts(58 are brought into engagement and the circuit through the solenoid Gis closed, as previously described, from power wire 90, by \conductor07, contacts (38 conductor 98.and branch conductor 2, and the type wheelis shifted to the left tobring either the second or third'transverse rowof type in line with the printing hammer. After the side shift of thetype wheel, it is rotated to bring the desired type to the printingpoint by closing the energizing circu it through one of ten of thebranches, number 5 to 14 inclusive. The branch circuits numbered 5 to 12as before, are arranged to selectively operate the sets of stops D, D Dand D and the set of stops E, E", n and E which, when or four steps tobring the selected type to the printing point. Branches 13 and 1.4 arearranged to close the circuit directly through the type wheel rotatingmag nets B and B (without first actuating any oithe movable. stops) sothat the wheel may be rotated in one or the other direction five. stepsuntil arrested by the engagement of the shifter-arm 109 with one or theother of the fixed stops C or D". As before, the shifter mechanism forrotating the type wheel cooperates, when actu ated, with the contacts 85or 89 to close the hammer operating circuit through the solenoid N. Oneof the type on wheel A lies at the printing point, and to effect the imr ssion of the type, the circuit is closed through branch 15 anddirectly through the hammer-actuating solenoid N. If the type to beselected lies in the longitudinal row in line with the hammer, the wheelis first shifted laterally to bring the same .to the printing point andthe circuit is then closed directly through branch 15 and solenoid N tooperate the printing hammer without rotating the type wheel. If thecharacter is in the transverse row of type in line with the printingpoint, the wheel is rotated to the proper extent, with-' out firstshifting the same endwise and the hammer actuating circuit isautomatically closed as before by the shifter 109. The other charactersmust be brought to the printing point by continuing the laterally andretary movements. Thus one character may be printed without shifting thetype wheel at all, thirteen by variably shifting the wheel with onemovement only and the remainder of the forty-four characters bycombining the two variable movements in different directions. Thevariable shifts moreover, are not step-by-step but the type wheel isquickly moved.by a single throw in one and the other direction.Moreover, no time is lost in restoring the parts to normal position,since as soon as the printing hammer is actuated the contacts 90 aredisengaged to open the circuit through the several oper-' ating magnetsand all shifted parts are instantly returned to normal position by theirrestoring springs. The type Wheel may thus be operated with greatrapidity and certainty to record the succeeding characters of themessage.

Various means may be employed to selectively control the flow of currentthrough the several br-ahch con ductors 1 to 15 inclusive. The selectivemeans in turn is controlled by the line circuit over which the mes sagesare transmitted, the various characters being represented by variablymodifying the circuit impulses over the line in keeping with a suitablecode.

In Fig. 7 is illustrated one arrangement of electric selector meanswhich may be employed. In this arrangement, the line circuit. 125extendsfrom the transmitting station, through a set of relays 126, atthe receiving station, and then to ground. These relays responddifferently to the varied line impulses, for example, to strong positiveand negative and weak positive and negative impulses respectively, asindicated.

The armatures of the first aud second relays which re spond to thestrong impulses are connected to battery 94 by a conductor 127, and thearmatures of the third and fourth relays are connected to the backcontacts of the first and second relays by conductors 128. A set ofconductors 130 are connected to the front contacts of the several relaysand are selectively connected to the battery or other source of power bythe operation of the relays 126 in response to varied line impulses. Theset of conductors 130 are connected to a set of transfer switches 131,to the back contacts of which a set of branch conductors 132 areconnected, so that the couductors 1.30 are normallyconnected at thispoint at the branches 132. A relay 133 having oppositely wound coilsorcoil sections, is arranged to actuate the transfer switches 131, atthe end of the first line impulse to shift. the connection of theconductors 130 from the branch conductors 132 to a set of conductors134, which are connected to the first contacts of the switches .131. Ineach of the branch conductors 132 is arranged a relay .135, and eachrelay is arranged to actuate a switcharm 136 and a second lockingswitclearm 137. I In this arrangement of selecting means, each characteris represented by three modified lineimpnlses. At the first lineimpulse, the circuit may be traced from battery 94, by conductor ]27 tothe armature of one of the line relays 126 (operated in accordance withthe character of the line impulse) to one of the conductors 130, and oneof the branches 132 and the corresponding relay 135, thence by aconductor 138 and a conductor 139 (common to all of the relays 135)through one of the coils of transfer switch relay 133 and back tobattery by return wire 95. Oneof the switches 137 then actuated, closesa circuit from battery wire 96. conductors 140, 141, switch 137.conductor 142, through the coil of the magnet 1335. which has beenenergized and bya common conductor 143 through the. opposite coil oftransfer.

switch relay 133 and back by return wire 95. The shifted switches 136and 137 are thus locked .in shifted position after the first.lineimpulse has ceased The. circuit is closed. through the oppositelywound coils of transfer switch relay 133 beforc it can operate, and asthe coils balance each other. the swift (hes 131. are not moved untilthe essation of the first line impulse opens the circuit through thebranch coinluctor 132 and one of the coils of the relay 1.33. Switches131 are then shifted to change the connection of the eonductors 130 fromthe bran hes 132 to the set of condur'tors 13-1, and the transferswitches, together with the selected switches me and 137 are lot-lied inshifted position. J

The set of switches 131i. selectively control the branch circuits 1,2.21 and -1 leading to the operating path of the printing nn-chanism. Theselected switch 136. closes a circuit from battery wire 96. conductorsHO and 141. selected switch 136 and one of the branches 1. 2. 3 or 4 1oeffeet the side shift of the type wheel. The form of printing apparatusshown in Figs. 6 and 7 does not utilize branch- 1. controlledbythe firstrelay .135. so hat if the wheel is not to be shifted laterally, thefirst line impulse selects this relay and merely serves to operate thetransfer switches 131.

The set of conductors 121-1 lead to a seconds-e1 of transfer switches 114 to the back contacts of which a set of branch condncton 116 are conneted. v.\ relay 116 I conductors 5 to inclusive, which lead to the operatswitch 153.

' ing switch 131, conductor 134 and switch. 144, to one of havingoppositely wound coils or coil sections, is ar- 1 ranged to shift theswitches 144 at the cessation of the second line impulse to change theconnections of the conductors 134 from branch conductors 145 to thebranches 147 (three in nuinber) which are connected to the frontcontacts of the transfer switches 143. In each of the branch conductors1.45 is arranged a magnet 148, each controlling a set of switches. Thefirst n1ag net 148 is arranged to operate the set of switches 149, andthe second, third and fourth magnets respectively operate the sets ofswitches 150, 151, and 152. There are three switches as shown in each ofthese sets and they control the flow of current throngh the branch ingparts for effecting the rotation of the type wheel and the independentoperation of the printing hammer. Each magnet is also arranged tooperate a locking At the second line impulse, the local operating circuit is closed as follows: from battery 94 by conductor 127, to thearmature of one of the line relays 126, thence by one of the conductors130, the correspondt'he branch conductors 145, through the coil of thecorand B- responding magnet 148, conductor 154 and common conductor 155through one of the coils of transfer switch relay 146, and by returnconductor 96 to battery. One of the sets of switc ies 149, 150, 151 or152 corresponding to the selected magnet 1.48 is then shifted and lockedin shifted position by the operation ofthecorresponding locking switch153. The latter closes a circuit as follows: from battery 'wire 96 bycommonconductor 157, conductor 158, the selected locking switch 153,conductor 159 through the coil ofthe selected magnet 148, by conductor160, and common conductor 161 through the opposite coil of transferswitch relay and back to battery as before by conductor 95. The oppositecoils of transfer switch relay Htiare thus both energized, and, as theybalance each other, the relay is not actuated until the cessation'of thesecbnd line impulse At this time, the circuit through one of the coilsof relay 146 is opened and transfer switches 144 are actuated to shiftthe connection of the conductors 134, from the set of branches 145 tothe set of branches 147. I The locking, circuit controlled by theshifted locking switch 153 is held however, in closed condition throughthe selected magnet 1.48 and through one of the coils of relay 146, sothat one of the sets'of switches 149, 150, 151 and 152, and the set oftransfer switches 144 are shifted and locked in shifted position bythesecond line impulse of the signal.

Each one of the three branch conductors 147 is connected as shown to oneof the three switches in each, of thesets 149, 150, 151 and 152. Asstated, each character is represented by three line impulses. At thethird line impulse, the local circuit is closed as follows: from battery9 by conductor 127, the armature of one of the line relays l2ti,'one. ofthe conductors 130, through the corresponding switch 131, conductor 134and switch 144 to'one vof the branch conductors 147, thence to one ofthe switches in that. sep'l 49, 150, 151 or 152, which have beenpreviously selected andshifted by the second line impulse, and

thenee to one oi the branches 5 to 15 inclusive, and

through the operating Viously described.

As above stated, branches 5 to 12 inclusive, .control the stop-actuatingmagnets-which effect the variable rotation of the type wheel. Branches13 and 14 directly control the type wheel rotating magnets B withoutiirst operating the one of the stop magnets. If it is not necessary torotate the wheel to bring the desired type to the printing point, thecircuit is directly closed through branch 15 and hammer actuating magnetN. g

The controlling circuit through the selecting means parts of themachine, as preas well as through the printing apparatus, is broken assoon as the printing hammer is actuated to disengage the contacts 90 inbattery wire 96, and all parts are immediately returned to normalposition, and are ready to receive the succeeding signal and record thecharacter corresponding thereto. This same selector" means could beemployed to control the operation through the set of branches whichgovern the operation of the printing mechanism diagrammaticallyillustrated in Fig; I. The controlling branch conductors arecorrespondingly numbered in Figs. 7 and S.

The particular electric selector means set forth forms no part of thepresent invention, and other arrangements. may be employed forselectively control-'- ling the flow of current through the set ofconductors leading to the operating parts of the printing mechanism. i

It is obvious that numerous changes may be,made in the details ofstructure and arrangomentof parts without departure from the essentialsof the invention. For example, the type-wheel or carrier may besegmental in form, if desired.
